The layer that I select is where I get the url from for the IdentifyTask. That doesn't work b/c IdentifyTask wants a service url.
Question 1: How do I return the service url from a feature layer?
Question 2: How do I figure out which layer, in the service, that I need for the IdentifyParameters.layerIds array?
Note, if I hard code a service into my code, the IdentityTask call back does return a proper response. I just need the middle goods to finish this.
